Question

A clever undergraduate, Grace N. Poise, hypothesizes that people under 30 are more humorous than people over 30. She tests this hypothesis by randomly selecting 4 people over 30 from the telephone book and 4 people under 30 from university registration lists. She gives each research participant the Humorous Speech Scale, which measures humor on a Likert-type scale from 1 to 10. The scores are listed below. Based on the T score obtained in number 14 we would reject the null hypothesis at the p=.005. the T score is 3.098
